100w power amplifier using STK404 integrated circuit


Posted on Feb 4, 2014

A very high power and efficiency 100w power amplifier electronic project can be designed using the STK404 audio power amplifier hybrid ICs that consist of optimally-designed discrete component power amplifier circuits that have been miniaturized using SANYO`s unique insulated metal substrate technology. This audio power amplifier use will provide

a maximum of 100 watt output power on a 6 ohms load with 0. 4% THD. Using the same IC, can be obtained an output power of 150 watts with 10% THD. Because of the power dissipation, audio power IC must be mounted on a heatsink. Therefore, the thermal resistance that satisfies all requirements of these power audio amplifier (for a guaranteed ambient temperature of 50 °C) is 1. 48 °C/W.
